Build: Stop using precompiled headers (PCH)
This had very bad interactions with ccache, often leading to rebuilds with 100% cache misses, etc. Ali says it wasn't that big of a speedup in the end anyway, so let's not bother with it. We can always bring it back in the future if it seems like a good idea.
